Abstract: A bicycle chain comprises a first inner link plate. The first inner link plate comprises a first end portion, a second end portion, and a first intermediate portion. The first end portion includes a first opening, a first chamfered section, and a first chamfer-free section. The first chamfer-free section is provided in at least a first chamfer-free angular range when viewed from an axial direction parallel to a first center axis. The first chamfer-free angular range is defined from a first circumferential end of the first chamfered section to a first inner-link longitudinal centerline of the first inner link plate. The first chamfer-free angular range is equal to or greater than 30 degrees with respect to the first center axis.

Abstract: A bicycle rear sprocket comprises a sprocket support member, a first attachment portion, and a second attachment portion. The sprocket support member comprises a first support member and a second support member. The first support member includes a first radially outer portion and a first radially inner portion. The second support member includes a second radially outer portion and a second radially inner portion. The first support member faces the second support member in the axial direction to define an axial gap provided between the first support member and the second support member in the axial direction. The first radially outer portion of the first support member is configured to be attached to the second radially outer portion of the second support member via a bicycle sprocket positioned between the first attachment portion and the second attachment portion in the axial direction.

Abstract: A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-curvature limiting protuberance. The sprocket body is configured to be rotatable about a rotational center axis. The plurality of sprocket teeth extend radially outward from an outer periphery of the sprocket body. The at least one chain-curvature limiting protuberance is configured to limit axial curvature of a bicycle chain engaging with an independent neighboring bicycle sprocket which is adjacent to the bicycle sprocket without another sprocket between the bicycle sprocket and the independent neighboring bicycle sprocket. The axial curvature is curvature of the bicycle chain relative to the bicycle sprocket when viewed from a radial direction perpendicular to the rotational center axis. The at least one chain-curvature limiting protuberance is disposed on at least one of an outward facing side and an inward facing side.
